Scott Mitchell Is A Bit Hefty These Days; To Appear On Biggest Loser

Mitchell, who once checked in at 240 during his playing days, ballooned up to 366 pounds (!!) since retiring in 2002.

While the 46-year-old Mitchell made his bones as a quarterback for the Lions, he may be best remembered for parlaying his sub stint for an injured Dan Marino in 1993 into a starting role with the Detroit Lions one year later.

These days, Mitchell is a bill collector in Utah.

Meanwhile, former New England Patriots offensive lineman Damien Woody will also appear on the program. Woody checks in just south of 400 pounds these days.
